BOX-STRAP SEAL.

To all whom it may concern:

Be it known that I, WINFRED MUDGE BROOKS, a citizen of the United States of America, and a resident of East Orange, in the State of New Jersey, have invented certain new and useful Improvements in Box- Strap Seals, of which the following is a specification.

The object of this invention is to provide a simple, and efficient seal for metal box straps capable of resisting heavy tension on said straps.

The invention consists in a novel auxiliary sleeve part, of a type similar to that shown is my pending application Serial No. 223,922, the particular construction of which is hereinafter fully described.

One sheet of drawings accompanies this specification as part thereof in which like reference characters denote like parts.

Referring to the drawings Figure 1 shows the sheet metal blank for one type before folding into a sleeve; Fig. 2 shows a top view of Fig. 1 after folding into a sleeve; Fig. 3 shows a top view of this type of seal after sealing. Fig. 4: shows a sheet metal blank for a second type of the improved seal before folding into sleeve form; Fig. 5 is a top view of the second type seal after folding into sleeve form; Fig. 6 shows a top view after sealing and Fig. 7 shows a section taken on the line mm of Fig. 3. Figs. 8 and 9 are side views of type one and type two seals, respectively, after sealing.

The improved seal is preferably constructed of substantially rigid sheet metal cut in such shape as to be adapted to be folded over on two parallel lines to form a substantially rectangular sleeve, having a top a, parallel sides 6, and bottom 6, and adapted to receive the crossed and overlapped ends of a box strap, d. On the lines of the proposed folds, B or U shaped holes are stamped as shown in Figs. 1 and f respectively in such manner that upon folding into sleeve form, 0 07 are formed on each side of the top, the sleeve being cut away from each side and from beneath each of said lips. The metal is stamped and folded into sleeve form at the factory and in this form is ready for use.

In operation the box strap d is passed around the box or bale to be fastened and the ends threaded from opposite ends through the auxiliary sleeve part a and Specification of Iietters Patent.

drawn by any suitable device to the desired tension. The lips c, 0 are then depressed by some suitable tool, bending down seal shown in Figs. 1, 2, 3, 7, and 8 by modifyin the length of the pointed lips 0 they can e made to project below the bottom of the sleeve and utilized to tack the entire seal securely to the box. The type of seal shown in Figs. 4, 5, 6, and 9, having square prongs or substantially square is particularly adapted for use with bales or burlap covered pareels having no protruding points to snag or tear the cover.

Modifications of the size, shape, and proportions of size, shape and number of the prongs will readily suggest themselves for particular purposes to those skilled in the art.

tion, I claim:

1. A seal for box straps comprising the overlapped ends of a box strap, an auxiliary metal sleeve adapted to embrace a portion of their edges and having a top, outwardly directed lateral lips on each side of said top, said sleeve on the sides and beneath said prongs being cut away, said lateral lips being adapted to being depressed and bent down together with the subjacent portions of the box strap substantially as specifiec 2. A seal for box straps comprising the overlapped ends of a box strap, an auxiliary sleeve adapted to receive said strap ends provided with a top, outwardly pointing lateral prongs on each side of said top, and adapted to being depressed together with the subjacent portions of the box strap until the points ofsaid prongs point downward and extend below the bottom of .the sleeve, substantially as specified.

3. An improved box strap seal consisting of a sleeve adapted to receive the crossed and overlapped ends of a box strap, said sleeve having a top part, outwardly pointing lateral prongs formed in said top part on each side, said sleeve being cut away from. the sides of and from beneath said prongs Eubstantially as and for the purposes speci- 4. An improved box strap seal consisting of a sheet metal sleeve part having a top,

sides, and bottom, a plurality of outwardly pointing V-shaped lateral lips on each side" Copies 01 this patent may be obtained for fivev cents each, by addressing the Commissioner of Patentsu Washington, D. .6."
